DviRamp
The DviRamp keyword enables control of the Miranda DVI-Ramp external device. The DVI-Ramp outputs
a standard definition serial digital video signal (SMPTE-259M-C) or a high-definition serial digital video
signal (SMPTE-292M).
NOTE Enable this keyword only if you are using the Miranda DVI-Ramp external device. The DviRamp keyword
is automatically commented out if the application installation script detects an NVIDIA
®
SDI card connected to
the system.
The DviRamp keyword uses the following syntax
DviRamp <serial port>, <baud rate>, <parity>, <size>, <stopBits>
Is:Where:
The type of connection to the DVI-Ramp external device. The values are:
<serial_port>
■ ttyS0 for a DVI-Ramp1 connected on a serial port.
■ usb/dviramp for a DVI-Ramp1 connected on a USB port using a USB-Serial
adaptor.
■ usb/dviramp2 for DVI-Ramp2 connected on a USB port.
The baud rate used to communicate with the DVI-Ramp.
<baud rate>
The parity setting to communicate with the DVI-Ramp. It can be set to EVEN, ODD,
or NOPARITY.
<parity>
The number of transmitted bits per packet.
<size>
The size of the stop bit.
<stopBits>
Example of use
DviRamp ttyS0, 38400, none, 8, 1
VideoPreviewDevice
The VideoPreviewDevice keyword specifies the device used for the graphics-to-video display. Specify entries
for the resolutions of the projects on which you will be working as well as the resolutions supported by your
hardware configuration.
The init.cfg file contains all supported tokens for the VideoPreviewDevice keyword. The project configuration
file will determine which one of these should be enabled for a given project.
VideoPreviewDevice is also used in conjunction with the VideoPreviewWindow keyword in the project
configuration template files; VideoPreviewWindow specifies the width and height of the window and the
refresh rate. See VideoPreviewWindow on page 92.
When the application is started and a project is selected, the VideoPreviewWindow must match one of the
VideoPreviewDevice entries. If no match is found, graphics-to-video output is unavailable.
The VideoPreviewDevice keyword applies to workstations configured with either a Miranda DVI-Ramp
external device, a NVIDIA SDI card, or graphics readback (SD timings only) if the hardware is not available.
